While Porsche may be relatively new to the four-door game, Maserati has been building the Quattroporte with few interruptions since 1963. But like its rival from Stuttgart, the Trident marque is rapidly shifting from a sports car company primarily to a manufacturer of high-end family transportation.

Then they made a video about their cleverness and posted it on the Internet. The team spent some time whipping around the Balocco Proving Ground with chief test driver Fabrizio Galvan at the controls to evaluate the sedan's new drivetrain
